Am I a POS for not feeling anything about my grandma dying?

My grandma is not dead but she's dying, she's 90. Every day she suffers greatly from various diseases and conditions e.g. ulcers, diabetes ect. Today she had a massive black spot on her leg, it looks like an infection but the doctors haven't diagnosed what it is yet.

Anyway she's in really bad condition but i don't really feel anything. I feel sympathy for her, but I don't feel any like personal feelings. Like I feel the same sympathy for her as random people in like Ukraine or Gaza yk. I told my mum this and she got annoyed and called me cold hearted.

But i have never rly talked to my grandma, i cant even talk to her bc there's a language barrier. She also lives in Italy whilst i live in the UK, so i see her like once a year for like a week or 2. So for me i feel no connection.

Anyway am I a POS for this.
